I'm helping a friend with a G3 white iBook (the one with two USB ports).
He replaced the hard drive himself a couple of weeks ago with a bigger
one. It worked OK for awhile, but now there's a problem: on startup, the
hard drive apparently can't be found. We just get the flashing question
mark icon. I tried booting from an Apple hardware test CD, and that
program claims that there's no hard drive present, although the rest of
the machine passes the hardware tests.
Any ideas as to why the replacement hard drive would work OK for awhile,
